SPECIFICATION forming part of Letters Patent No. 7 56,105, dated March 29, 1904.

Application filed October 8, 1903.

Be it known that I, HENRY M. ETTER, aciti- Zen of the United States, residing at Marion, in the county of Franklin and State of Pennsylvania, have invented certain new and useful Improvements in Pump-Heads, of which the following is a specification.

This invention belongs `to the type of pumps operable either by hand or windmill power, and relates most especially to the head, the means for throwing the operating-handle into and out of gear with the rack-bar, and to the means for relieving the operator of the deadweight incident to depressing the outer end of the handle for lifting the piston and the column of water.

The invention aims to improve the general construction of the'pump-head, whereby the same may be cast and adapted to'be readily applied to or disconnected from the upper portion of the pump-body without requiring the use of fastenings other than necessary to secure the parts of the castings constituting the pump-head.

A further purpose of the invention is to disconnect the toothed segment from the rackbar when it is required to operate the pump solely by means of the windmill or like power, whereby the necessity for removing the handle is obviated, the wear on the parts minimized, and the work reduced to the smallest amount possible.

The invention also contemplates combining with the rack-bar a pump-rod and novel form of yielding connection, 'whereby the initial movement of the operating-handle to lift the column of water is relieved of the shock and strain incident to starting a load from a point of rest, and as a result the operation of the pump by hand is less fatiguing than required in pumps of this type as generally constructed.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modication, still the preferred embodiment of the Serial No. 176,300. (No model.)

invention is illustrated in the accompanying drawings, in which- Figure l is an elevation of one-half of the pump-head,showingthe rack-bar, toothedsegment, connection between the rack-bar and pump-rod, and the upper portion of the pumpbody. Fig. 2 is a horizontal section on the line .X X of Fig. l. Fig. 3 is a detail perspective view of the toothed segment and the bearings therefor.

Corresponding and like parts are referred `to in the following description and indicated in all the views of the drawings by the samel reference characters.

The pump-body is indicated at 1 and is provided at its upper end with the reducedor neck portion 2,having a bead or outer ange 3 at its upper end. The body of the pumpl may be of any design'or make.

The pump-head is composed of similar halves, sections, or parts, preferably cast and adapted to be secured by bolts or like fastenings 4, passed through transversely-alining openings of the parts. Between the parts or halves of the pumpe-head are located the rackbar 5, roller 6, and toothed segment 7, the latter being adapted to intermesh with the teeth of the rack-bar 5 when it is required 'to operate the pump by hand. The operatinghandle (not shown) is adapted to be connected in any substantial way to the shank of the toothed segment.

pump-body and is prevented from upward displacement by means of the bead or flange 3 and from downward movement by the combined action of said bead and tl'ie part of the pump-body at the base of the neck portion 2.

The lower portion of theY pump-head encircles the neck portion 2 ofthe A bearing 8 is journaled in each half of the pump-head and is providedat its inner end with aflange 9, whichlimits the outward movement of the bearing, and at its outer portion with an angular extension 10, to which is fitted a handlell for rotation of the bearing 8 to throw the toothed Vsegment into and out of gear with the rack-bar. An opening l1 is formed in thev inner end of each bearing 8 and IOO has an eccentric arrangement and is adapted to receive the journal or trunnion 12 of the toothed segment. Itis to be understood that a journal or trunnion 12 is provided at each side of the toothed segment and may be an integral part thereof or applied thereto in any manner. The journals or trunlions 12 are in transverse alinement and enter the openings 11 of the bearings 8 and pivotally support the toothed segment. By having the openings 11a eccentric with reference to the bearings obviously a turning of said bearings about their axes will effect a movement of the toothed segment toward or away from the rack-bar. When the bearings 8 are turned to bring the openings 11'JL nearest to the rack-bar, the latter and the toothed segment are in mesh or gear, and when said bearings are turned to move the openings 11 farthest away from the rack-bar the toothed segment is thrown out of gear with the rack-bar. The movement of the bearings 8 on their axis is effected by means of the handles 11, which are weighted so as to hold said bearings and the toothed segment in either of their extreme positions. Pins or stops 13 project laterally from the pump-head to engage with and support the handles 11 in either of their extreme positions.

An opening 14 extends upward from the lower end of the rack-bar 5 and receives the upper end of the pump-rod 15 and the coilspring 16, which surrounds the upper portion of the pump-rod and is confined between the stops 17 and 18. The stop 17 may be of any construction and, as shown, consists of a pin passed transversely through an opening at the upper end of the pump-rod. The stop 18 consists of a collar threaded into the lower end of the opening 14, and besides forminga support for the lower end of the spring 16 constitutes a guide for the pump-rod 15, thereby preventing lateral play of said pump-rod in the opening 14 and obviating tackling noise and the wear incident to such pounding movement.

When it is desired to operate the pump solely by means of the windmill or other power, onel or the other of the handles 11 is operated to throw the toothed segment out of gear with the rack-bar 5, thereby obviating the necessity of disconnecting the handle from the segment and avoid the wear and tear incident to operation of the toothed segment when the pump is worked by power other than hand. When the pump is to be operated by hand, the toothed segment is thrown into meshing relation with the rack-bar by operation of the handles 11 in a reverse direction. The mounting of the toothed segment in the manner disclosed also provides for adjustment thereof with reference to the rack-bar, as the toothed segment may be thrown out of gear and then adjusted to the required position and again thrown into gear, as will be readily comprehended.

Each of the handles 11 is formed with an extension 19, which when the handle is thrown outward engages under the stop 13 and limits the outward and downward movement of the handle, as will be readily understood.

Having thus described the'invention, what is claimed as new is- 1. In apump of the character described, and in combination with the pump-rod, the rackbar connected therewith and the toothed segment for cooperating with the rack-bar, bearings rotatably mounted, an eccentric connection between the toothed segment and said bearings, an Ioperating-handle applied to a bearing, and means for limiting the throw of said handle in each direction, to definitely hold the toothed segment either in or out of engagement with the rack-bar, substantially as specified.

2. In a pump of the character described, and in combination with the pump-rod, the rackbar connected therewith, and the toothed segment for cooperating with the rack-bar, a rotary bearing iianged at its inner end and having a projection at its outer end, an eccentric connection between the toothed segment and bearing, and an operating-handle applied to the projecting end portion of the bearing to eect turning thereof about its axis to throw the toothed segment either into or out of engagement with the rack-bar, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY M. ETTER.
